Use a contact group (formerly called a “distribution list”) to send an email to multiple people—a project team, a committee, or even just a group of friends—without having to add each name to the To, Cc, or Bcc line individually.
On the Navigation bar, click People.
Note: You can find People in one of two places on the Navigation bar.
If you're using the compact Navigation bar, click the People icon.
If you're using the expanded Navigation bar, click the word People.
Under My Contacts, select the folder where you want to save the contact group. Usually, you'll select Contacts.
On the Ribbon, select New Contact Group.
Give your contact group a name.
Click Add Members, and then add people from your address book or contacts list.
Note: To add someone who is not in your address book or contacts, select New E-mail Contact.
Click Save & Close.
To learn how to use your new contact group, see Send an email message to a contact group.
